Why can't the installed ETC be recognized?

[VonHarper]

The reasons why the installed ETC cannot be recognized are: 1. The ETC card is not inserted correctly into the electronic tag; 2. The electronic tag is loose or detached, and needs to be reactivated at the original processing point or any ETC service point on the highway; 3. Lane malfunction; 4. The electronic tag is faulty. ETC is an electronic toll collection system, also known as an automatic road toll system. It is a road toll method specifically designed for toll roads, commonly found on highways, bridges or tunnels with toll policies, and certain sections of urban centers to alleviate urban traffic congestion. Through microwave-dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane of the toll station, the system uses computer networking technology to conduct background settlement processing with the bank, thereby achieving the purpose of vehicles paying tolls without stopping at road and bridge toll stations.
